Well, I'm not sure if the 3 year track is adjusted any differently, but the tuition and fees for each year (going full time) for the 2 year track is $8350 total for one year. This is coming directly from my financial aid award summary, which I received tonight. So total for the 2 year track comes out to $16,700 just for tuition and fees.
They estimate the other expenses related to cost of attendance (housing, food, transportation, books) to be another $15,918 per year so TOTAL estimated cost of attendance including both tuition, fees, and other living expenses comes out to $24,268 per year. Of course, this number could vary depending on your situation in life (living at home with parents, etc.). I am not sure what this number becomes for a 3 or 4 year track program though.
I assume that tuition costs would likely be the same, especially if you're paying for the same number of units. However, the other living costs related to going to graduate school would probably be more because you're having to go to school for another year or two. I hope that helps some!
I grew up in San Diego my whole life also so my support system is there as well. I will save some of the costs of attending graduate school by living with either my mom or dad. I have mixed feelings about that, but I am grateful for the opportunity.
Congratulations by the way on acceptances to both SDSU and Monterey Bay! Good luck on your decision
